AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–03–03, which applies to certain 

ATR–GIE Avions de Transport Re ́gional 

Model ATR72 airplanes. AD 2021–03– 

03 requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

Since the FAA issued AD 2021–03–03, 

the FAA has determined that new or 

more restrictive airworthiness 

limitations are necessary. This proposed 

AD would require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this proposed AD by September 3, 

2021.

Background 

The FAA issued AD 2021–03–03, 

Amendment 39–21406 (86 FR 11103, 

February 24, 2021) (AD 2021–03–03), 

for certain ATR–GIE Avions de 

Transport Re ́gional Model ATR72 

airplanes. AD 2021–03–03 requires 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. The FAA 

issued AD 2021–03–03 to address 

fatigue cracking and damage in 

principal structural elements, which 


khammond on DSKJM1Z7X2PROD with PROPOSALS
38240 Federal Register / Vol. 86, No. 136 / Tuesday, July 20, 2021 / Proposed Rules 

could result in reduced structural 

integrity of the airplane. 

Actions Since AD 2021–03–03 Was 

Issued 

Since the FAA issued AD 2021–03– 

03, the FAA has determined that new or 

more restrictive airworthiness 

limitations are necessary. 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0020, 

dated January 15, 2021 (EASA AD 

2021–0020) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all ATR–GIE 

Avions de Transport Re ́gional Model 

ATR72 airplanes. EASA AD 2020–0020 

refers to ATR ATR72 Time Limits 

Document. Revision 18, dated October 

9, 2020. Airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued after October 9, 2020, must 

comply with the airworthiness 

limitations specified as part of the 

approved type design and referenced on 

the type certificate data sheet; this AD 

therefore does not include those 

airplanes in the applicability. 

This proposed AD was prompted by 

a determination that new or more 

restrictive airworthiness limitations are 

necessary. The FAA is proposing this 

AD to address fatigue cracking and 

damage in principal structural elements, 

which could result in reduced structural 

integrity of the airplane. See the MCAI 

for additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0020 describes new 

or more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This material is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is proposing this AD 

because the FAA evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would retain all of 

the requirements of AD 2021–03–03. 

This proposed AD would also require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations, which are 

specified in EASA AD 2021–0020 

described previously, as incorporated by 

reference. Any differences with EASA 

AD 2021–0020 are identified as 

exceptions in the regulatory text of this 

AD. 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 

actions (e.g., inspections). Compliance 

with these actions is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by this proposed 

AD, the operator may not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply 

with 14 CFR 91.403(c), the operator 

must request approval for an alternative 

method of compliance according to 

paragraph (m)(1) of this proposed AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA initially worked with 

Airbus and EASA to develop a process 

to use certain EASA ADs as the primary 

source of information for compliance 

with requirements for corresponding 

FAA ADs. The FAA has since 

coordinated with other manufacturers 

and civil aviation authorities (CAAs) to 

use this process. As a result, EASA AD 

2021–0020 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0020 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

the EASA AD does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in the EASA AD. 

Service information specified in 

EASA AD 2021–0020 that is required for 

compliance with EASA AD 2021–0020 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2021–0508 after the FAA final 

rule is published. 

Airworthiness Limitation ADs Using 

the New Process 

The FAA’s process of incorporating 

by reference MCAI ADs as the primary 

source of information for compliance 

with corresponding FAA ADs has been 

limited to certain MCAI ADs (primarily 

those with service bulletins as the 

primary source of information for 

accomplishing the actions required by 

the FAA AD). However, the FAA is now 

expanding the process to include MCAI 

ADs that require a change to 

airworthiness limitation documents, 

such as airworthiness limitation 

sections. 

For these ADs that incorporate by 

reference an MCAI AD that changes 

airworthiness limitations, the FAA 

requirements are unchanged. Operators 

must revise the existing maintenance or 

inspection program, as applicable, to 

incorporate the information specified in 

the new airworthiness limitation 

document. The airworthiness 

limitations must be followed according 

to 14 CFR 91.403(c) and 91.409(e). 

The previous format of the 

airworthiness limitation ADs included a 

paragraph that specified that no 

alternative actions (e.g., inspections) or 

intervals may be used unless the actions 

and intervals are approved as an 

alternative method of compliance 

(AMOC) in accordance with the 

procedures specified in the AMOCs 

paragraph under ‘‘Other FAA 

Provisions.’’ This new format includes a 

‘‘New Provisions for Alternative Actions 

and Intervals’’ paragraph that does not 

specifically refer to AMOCs, but 

operators may still request an AMOC to 

use an alternative action or interval. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 23 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2021–03–03 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 136 / Tuesday, July 20, 2021 / Proposed Rules 38241 

The FAA estimates the total cost per 

operator for the new proposed actions to 

be $7,650 (90 work-hours × $85 per 

work-hour). 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Airworthiness Directives; Leonardo 

S.p.a. Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Leonardo S.p.a. Model A119 and 

AW119 MKII helicopters. This proposed 

AD was prompted by reports of 

abnormal play on the collective torque 

tube on two Model AW119 MKII 

helicopters. This proposed AD would 

require repetitive inspections of affected
